IN BRIEF Quantum physics and cosmology were born in the early 20th century. Quantum cosmology describes the early moments of the Universe. The concept of the quantum multiverse suggests an infinity of universes. Quantum gravity raises many questions about the nature of the Universe. Big Bang and particle physics: essential links. Projects on loop quantum … Read more
IN BRIEF String theory: fundamental theoretical framework in physics. Fundamental objects are vibrating strings. Elementary particles correspond to the different vibrations of strings. Famous for its ambition to be the “theory of everything”, unifying the forces of nature. Involves 11 dimensions in certain formulations. A necessary popularization to make science accessible. Exploration of local symmetries … Read more
IN BRIEF Hidden dimensions in the Universe: concepts and theories. Mechanism to confer mass to neutrinos. Physics of particles confined to surfaces called branes. Exploration of hidden variables in quantum physics. Kaluza-Klein theory and extra dimensions. Search for particles of the standard model and the graviton. Links with concepts of multiverse and time travel. Seeks … Read more
IN BRIEF Holographic principle: central concept in theoretical physics. Proposes that the information of a system can be represented on its surface rather than in its volume. Related to the study of black holes and their event horizon. Indicates a relationship between gravity and quantum. Suggests that our universe might be similar to a hologram. … Read more
